Abstract

A contour gauge of general type is analysed where 1-form (vector potential) is expressed as a contour integral of the 2-form (field strength) along an arbitrary contour C. For a special class of contours the gauge condition reduces to kμ(x) Aμ(x) = 0 where kμ(x) is a tangent vector to the contour C. A simple proof of the nonabelian Stokes theorem is given demonstrating the advantage of the gauge.
